(Engineering Machinery with High Strength Wear Resistant Steel Plates  ) 
-NM550

NM550 Wear resisting steel adopt the first Word Pinyin NaiMo and its HBW value to name the grade; 550  Show
the average brinell hardness of steel plate

1.NM550 belong to low alloy wear resistant steel

2.Named: NM550.

3.NM550 its average HBW is 550

(International Stipulation Range of HBW: ≥530).

4.The Delivery Status NM550: Qunched and Tempered .

5.Steel Plate size, Shape, Weight and allowable Deviation: should comply with the provisions of GB/T709.

6.Steel Surface Quality: conform to GB/T 3274;

7The provisions of this standard and acceptance inspection items of the reinspection rules shall comply with the provisions of
GB/T 17505.

8.Rolled Range: 3-80mm(Other thickness two sides negotiate)

9.Chemical and Mechamical Property: as following Table
